A list of G81 UBVRI secondary standard stars for CCD photometry is presente
d. Visual magnitude ranges from 9.7 to 19.4, and the B - V colour index var
ies from 1.15 to 1.97. The stars are grouped into 11 different fields, each
of them is generally observable in a single CCD frame. The stars are locat
ed near Landolt UBVRI equatorial standards, accessible to telescopes in bot
h hemispheres, and mainly within the 5 - 8 hours range of right; ascension.
Photometry, equatorial coordinates and finding charts are provided.
